Altaic etymology :

Comments:? Cf. also Turk. *üč (*öč) 'three' (ЭСТЯ 1, 641-642, Stachowski 254). The match is somewhat problematic, basically because of the absence of the TM cognate, shortness of the root and unclear suffixation. The basic phonological correspondence pointing to PA *ŋ- is, however, observed, and the parallel seems to be worth noting.
